#MissingType

Have you noticed we’re missing a few letters on Twitter?

Round Table Great Britain and Ireland are supporting the #MissingType campaign.

As a part of National Blood Week, we’re highlighting the fact that there are now 40% fewer new donations last year than the decade prior. To keep the nation’s blood stocks at a safe level, 204000 new volunteers need to be found.

Some of the most common blood types, including A,B and O are the ones most in demand.

NHS Blood and Transplant said: "This Missing Type campaign highlights that if not enough new people donate blood and these types were to go missing in years to come, there wouldn't be enough blood available when patients need it."
